Researchers create model to explore SARS-CoV-2 Omicron and Delta supremacy

In a new study, researchers have created a model to help identify the dynamics of Delta and Omicron infection in the US, as well as explore the effects of various factors on the overall COVID-19 pandemic.

Periconceptional maternal smoking associated with delay in embryonic development

Smoking by mothers during the period immediately before and after conception is linked to a delay in embryonic development, smaller foetuses at the time of the 20-week ultrasound scan, and lower birth weight.

Assessing the transmissibility of SARS-CoV-2 variants of concern

A new study investigated and compared the transmissibility of severe acute respiratory syndrome coronavirus-2 variants of concern.

The relative contagiousness of the Alpha, Delta, and Omicron SARS-CoV-2 variants

A new study, available on the arXiv* server, proposes a simple dynamic model for estimating the relative contagiousness of two variants of SARS-CoV-2, namely Alpha and Delta. Furthermore, it demonstrates how to compute the effective reproduction number for a new variant without contemporaneous sequencing results. This is important to assess the state of the pandemic in real-time.

Research links structural sexism and LGB discrimination with poor birth outcomes in the U.S.

New research links structural sexism, restrictive family planning policies, and structural discrimination against lesbian, gay, and bisexual (LGB) populations with increased risk of preterm birth and decreased birth weight - regardless of the sexual orientation of the person giving birth.

Study highlights benefit of mRNA boosters for SARS-CoV-2 following different initial vaccine types

A study by researchers from the United Kingdom finds no difference in the protection offered by mRNA vaccine boosters against the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) when comparing those that have received BioNTech/Pfizer vaccine as a primary course to those that have received Oxford/AstraZeneca.

Study identifies genetic link between early maturation and high aerobic performance in juvenile salmon

A study conducted at the University of Helsinki indicates that early sexual maturation and high aerobic performance in salmon have a genetic link that is already evident in juvenile salmon.

New simulation model shows how likely the SARS-CoV-2 virus spreads in different school settings

A year ago, the whole world discussed: is it irresponsible to send children to school during a pandemic, or do measures exist that can prevent corona clusters so efficiently that schools can stay open (or reopen)?

Balanced pollen diet reduces the negative effects of parasitic infestation for bumblebees

Bumblebees are important pollinators because they pollinate many different plant species and are extremely resilient. They can still manage to fly at temperatures that are too cold for other pollinators.

Impact of SARS-CoV-2 booster vaccination on Delta variant resurgence in Israel

In a new study, researchers constructed a discrete-time age-of-infection age-stratified transmission model to accurately determine the individual to population-level data on SARS-CoV-2 Delta surge dynamics in Israel

Study finds Omicron infection effectively induces immunity against itself and enhances protection against other variants in vaccinated individuals

Researchers investigated the effectiveness of the SARS-CoV-2 Omicron-variant induced immunity, whether it is cross-protective against other variants, and if earlier infection with the SARS-CoV-2 Delta variant offers protection against Omicron.
